Wils_SDSSJ162520.29+120308.7k rapid fading

   Rudolf Novak and Enrique de Miguel have reported most recent observations.
Combined with earlier observations by Gianluca Masi and Michael Richmond,
it has become evident that the object started rapid fading since July 12.
This evolution in unusually early (4-5 d after the full growth of superhumps),
and we should closely watch subsequent evolution.

   Quite interestingly, the nominal Pdot is positive between July 10 and 14
(dot(P)/P = +23(4)*10^(-5)).  This value is also rather unusual for this
superhump period.
